Embodiment 1

[0033] This embodiment adopts a four-stage medium-temperature drying method. Each drying section is fully enclosed, independent of each other, and does not interfere with each other. The dry hot air is processed by the hot air centralized treatment system and distributed to each drying room through the air duct. After the air is mixed, it is in contact with the material, and the high-humidity air is returned to the centralized processing device through the air duct, and part of it is discharged to the outside. The indoor temperature, humidity, moisture removal and air intake of the four drying chambers are intelligently controlled in proportion and according to the heat demand, and the process steps are carried out in the drying chamber.

[0034] Among them, the ambient temperature in the constant temperature and humidity drying room is 47°C, the ambient humidity is 84%, the wind speed is 3.5m / s, and the time for rice noodles to run in the room is 60 minutes;

[0041] Among them, the ambient temperature in the heating and drying chamber is 41°C, the ambient humidity is 79%, the wind speed is 2.5m / s, and the time for rice noodles to run in the chamber is 110min;

[0042]Among them, the ambient temperature in the main drying room is 45°C, the ambient humidity is 78%, the wind speed is 2.0m / s, and the time for rice noodles to pass through the room is 240min;

[0043] Among them, the ambient temperature in the drying room is 28°C, the ambient humidity is 76%, the wind speed is 1.5m / s, and the time for the rice noodles to pass through the room is 180 minutes;

[0044] The main physical and chemical indicators of the rice noodles dried by the four-stage medium-temperature drying process are as follows: the product moi...

Embodiment 3

[0046] Among them, the ambient temperature in the constant temperature and humidity drying room is 45°C, the ambient humidity is 82%, the wind speed is 3.0m / s, and the time for rice noodles to run in the room is 55 minutes;

[0047] Among them, the ambient temperature in the heating and drying room is 49°C, the ambient humidity is 81%, the wind speed is 3.0m / s, and the time for rice noodles to run in the room is 90 minutes;

[0048] Among them, the ambient temperature in the main drying room is 53°C, the ambient humidity is 80%, the wind speed is 2.5m / s, and the time for rice noodles to run in the room is 170min;

[0049] Among them, the ambient temperature in the drying room is 32°C, the ambient humidity is 79%, the wind speed is 2.0m / s, and the time for the rice noodles to pass through the room is 200 minutes;

[0050] The main physical and chemical indicators of the rice noodles dried by the four-stage medium-temperature drying process are as follows: the product moisture c...

Abstract

The invention discloses an intelligent rice noodle drying process. The prepared rice noodle sequentially pass through a constant-temperature and constant-humidity fixed-strip drying chamber, a heatingdrying chamber, a main drying chamber and an accomplishing drying chamber which are independent and closed for drying, wherein the environment temperature of the constant-temperature and constant-humidity fixed-strip drying chamber is 37 DEG C-47 DEG C, the humidity is 80%-84%, the wind speed is 2.5-3.5 m/s, and the passing through time is 55 min-70 min; the temperature of the heating drying chamber is 41 DEG C-51 DEG C, the humidity is 79%-82%, the wind speed is 2.5-3.5 m/s, and the passing through time is 90 min-110 min; the temperature of the main drying chamber is 45 DEG C-55 DEG C, the humidity is 78%-80%, the wind speed is 2.0-2.5 m/s, and the passing through time is 150 min-240 min; and the temperature of the accomplishing drying chamber is 28 DEG C-35 DEG C, the humidity is 76%-80%, the wind speed is 1.5-2.5 m/s, the passing through time is 180 min-250 min, the temperature control error in each drying chamber is less than or equal to +/-1 DEG C, and the humidity error is lessthan or equal to +/-5%. According to the intelligent rice noodle drying process, the problems of low yield and serious energy waste in the existing rice noodle drying process are solved, the constanttemperature and constant humidity in all drying chambers is achieved, so that the drying process is not affected by weather, seasons and climate conditions.

Description

technical field [0001] The invention belongs to the technical field of food processing equipment, and in particular relates to an intelligent rice noodle drying process. Background technique [0002] Rice noodle drying is a continuous water evaporation process, the key is to grasp the temperature and humidity of each drying process. The traditional rice noodle drying process is mainly based on temperature control and has no humidification device. It is difficult to ensure stable product quality. The indoor temperature and humidity are uneven, which is greatly affected by seasons and weather. Rice noodles are dried and dehydrated in an extremely unstable temperature and humidity environment, causing product Deformation, vertical and horizontal fracture, and brittleness lead to problems such as poor product quality stability and consistency, low yield, and serious energy waste. Contents of the invention [0003] The invention provides an intelligent rice noodle drying proce...
